Basically finished ordering stuff for my fuel system. I have -8 from the stock tank and stock pump, to the surge tank, then dual bosch 044 in parallel with -8 lines going to both sides of the fuel rail, and a -6 from the center of the fuel rail to the surge tank(FPR THAT I HAVENT ORDER YET INSERT HERE), and then -6 all the way back.

SO> I currently have a 3" intercooler core(cx racing) thats really not the best size, but totally works. Should I continue with that, or just order a good brand name 4" intercooler core? The intercooler is going to be mounted just like mr saito's is.

IMO, it is better to have more frontal area on an intercooler than more core thickness. Extra core thickness should come after your space constraint for frontal area has been maximized. The heat removed from the fins at the front of the intercooler will provide hotter air and less convective cooling as it travels through the core.

Well.... I maximized the frontal area I would say. I'm mounting my radiator in the rear. Hey, while we are at it, link me to a radiator I should buy with a couple fans! haha. Man I'm lazy. But yea basically there isn't much in front of the intercooler, and I was actually thinking about some ducting. I'm trying to make the intact piping as short as possible. http://photos.motoiq.com/photos/i-KK2cWqB/2/L/i-KK2cWqB-L.jpg
Thats the url to the photo of his intercooler. I hope that helps?

Anyone have any opinions on radiator line size? I would love to do some hardline aluminum or something.. Anyways, I still need to purchase a water pump(electric) and mount the radiator and stuff. I gave in and bought a manifold though.. Too cold to work outside and build one haha. Car should be together real soon here.

More pics! What manifold did you pick up? I'd like to see that fuel system setup for sure.

Also, I just picked up the obx manifold. Tons of good reviews on it as its a 666 copy, and they seem pretty strong. They made over a 1000hp with it so ill be good? ill be bracing it as well. I ditched the twin wastegate thing as I didn't think I should need to bleed off much boost
My fuel rail is getting here next wednesday, So Ill be able to finish up most of the install. Ill upload a shit load of pictures next weekend after the manifold gets here.sk8 or die

I order fuel rail stock from Threadstone or something. Ordered all my fittings from Anfittingsdirect or something. -8 male to 1/2 NPT on each end, and I haven't ordered anything for the return yet, but I'm guessing I'm going to have to weld a -6 in.

I'm stupid and should have bought a different manifold but it will do for now. My turbo is t3 exhaust housing split, but the manifold is t4 open(future turbo). So I built an adapter quick at work. 1/2" thick mild steel. Cold rolled. I still have to ball end it but I had to eat dinner and I'm impatient(I'll probably do it tomorrow).

Yes definitely an odd size. BMW just has to throw some curve balls in there. The strangest thread pitch combo I have seen is on my Land Cruiser the seat belt bolts are a 7/16-20. The reason I found for that is so that they do not get mixed up at the factory and use the wrong bolts because every other piece of hardware on the truck is metric.
